In Eq. \(\PageIndex{2}\), the forces in the \(y\) direction are \(n\) (in the \(+y\) direction) and the \(y\) component of the weight ( \(m g \cos \theta\) ) in the \(-y\) direction.
For example, if you're ever rented a moving van, the van will have an inclined plane (a "ramp") at the back of the truck. In the case of an inclined plane whose inclined length is \(L\) and whose high...For example, if you're ever rented a moving van, the van will have an inclined plane (a "ramp") at the back of the truck. In the case of an inclined plane whose inclined length is \(L\) and whose high end is at height \(H\), the mechanical advantage is found from \(W_{i}=W_{o}\), or The mechanical advantage of the inclined plane may be made arbitrarily large by increasing the length \(L\) of the plane.
